Question

In a favorable habitat and without natural predators, a population of reindeer is introduced to
an island preserve. The reindeer population t years after their introduction in 1990 is given by . F(t)=-0.125t^5+3.125t^4+4000. Estimate the number of reindeer on the island in 2007.

Answer 1

so if 1990 ---> t = 0
then 2007 ---> t = 17

F(17) = sub in t = 17 into your equation and evaluate

Answer 2

well, 2007 is 1990+17, so just plug in 17 for t.
